A method, device and system for determining the corresponding relationship between the spatial position of the handle and the code

Abstract

The embodiment of the invention discloses a determination method, device and system for a corresponding relation between a spatial position and a code of a handle. According to the method, the spatialposition of the handle and a grayscale image sent by a camera are acquired, and the handle emits infrared rays at preset flicker frequency f<handle>, wherein f<handle> is greater than f<camera>*K / 2C,f<handle> is the flicker frequency of the handle, f<camera> is refresh frequency of the camera, K is the number of scanning lines of a camera resolution, and C is the number of scanning lines occupied by the grayscale image of the handle; the grayscale image is obtained after the camera photographs the handle, and the grayscale image is in a black and white stripe shape; and the code of the handle under the spatial position is determined according to the grayscale image. Through the determination method, device and system, the situation that when a processor is disturbed by the color of a background article when recognizing the code of the handle according to a handle color collected by the camera can be effectively avoided, the corresponding relation between the spatial position and thecode of the handle can be accurately determined, and the interaction precision of a VR system is improved.

Description

technical field [0001] The invention relates to the field of virtual reality technology, in particular to a method, device and system for determining the corresponding relationship between the spatial position of a handle and a code. Background technique [0002] Virtual reality (English: Virtual Reality, abbreviation: VR) technology generally refers to computer simulation technology that can create and experience virtual worlds. The basic principle of the VR system is as follows: First, a computer is used to generate a virtual scene, and then through a specific interactive device, the user is immersed in the virtual scene, thereby guiding the user to have a sense of being there. [0003] A VR system usually includes a processor, a camera, a headset, and a controller. The camera, the head-mounted device and the handle are respectively connected to the processor. Wherein, the head-mounted device is a human-computer interaction device using virtual reality technology, for ex...

Problems solved by technology

[0005] The purpose of the present invention is to provide a method, device and system for determining the corresponding relationship between the spatial position of the handle and the code, so as to solve the problem that in the prior art, when determining the corresponding relationship between the spatial position of the handle and the code, it is easy to be interfered by the color of the background item itself. Causes errors in determining the corresponding relationship between the spatial position of the handle and the encoding, generates wrong feedback information, and reduces the interaction accuracy of the VR system
